It got more tricky to pick the logs. When the bug is hit, the device vanishes from USB listings. rrs@learner:~/.rrs-home/Community/fitbit-googlefit (master)$ sudo lsusb Bus 003 Device 002: ID 8087:8000 Intel Corp.

So I removed the xhci-hcd module, and also the xhci-pci module which was using xhci-hcd Then I loaded the xhci-hcd module and dmesg looked clean. But the moment I loaded the xhci-pci module, I ran into the same dmesg logs again.
